摘要: The paper deals with hydrocracking on metal-loaded zeolites. A fundamental approach is presented in which the detailed reaction network of feed components a complex feedstock retained to maximum extent. kinetics are developed terms elementary steps and single events involved reactions. Plausible assumptions thermodynamic constraints limit number kinetic parameters. These do not depend chain length hydrocarbons affected by composition. Certainly, chemical analysis still imposes certain degree lumping networks, but extent reflected present day models.
